It is not recommended to use an LRA (Locked Rotor Amperage) higher than what is indicated on the compressor because it can damage the compressor and the electrical system. Using a lower LRA may not provide enough starting current for the compressor to function properly. It is best to follow the manufacturer's guidelines for LRA when selecting a replacement compressor.
Read the tag on the condenser, it will be noted as LRA. Be sure to check the LRA for the fan as well and add them together for the total. If it is not listed on the tag it will certainly be listed seperately on both the compressor and the fan motor. LRA = Locked Rotor Amps.
Ah, what a lovely question! One ton is equal to 12,000 British Thermal Units per hour (BTU/hr) or 3.517 kilowatts. Isn't that just a happy little conversion to know? Just remember, whether it's tons or LRA, every unit has its own unique beauty.
You add up all of the current draws, 1 + 8.5 + 1 + 10 = 20.5 amps. If you say that all of this load is on a 15 amp circuit then you must get a lot of tripping of the breaker. If the equipment was on a two pole 15 amp breaker then there would be no problem as the motor current would only be half and the rest of the equipment would operate on the three wire feeding this equipment's neutral. To over come the starting current of the motor, a factor of 250 % should be used. 10 x 250% = 25 amps. This type of load should be on a breaker of its own. A generator that will start and run this load should be 35.5 amps x 120 volts = 4260 watts. If like you say its is all on a 15 amp breaker then W = A x V = 15 x 120 = 1800 bare minimum.
Zirconia, ZrO2, was synthesized by calcination of pure, sulfate-impregnated, and phosphate-impregnated Zr(OH)4 at different temperatures in the range from 600 to 1100°C for 5 h. Weight variant and invariant processes involved were monitored by thermogravimetry, differential thermal analysis and differential scanning calorimetry. The bulk structure and phase composition of the zirconias thus produced were characterized by X-ray powder diffractometry, infrared absorption spectroscopy and Raman scattering spectroscopy. The results have been correlated, so as to reveal the influence of the sulfate and phosphate additives on the zirconia polymorphic transitions as a function of temperature. Accordingly, phosphate species have been revealed to stabilize or influence stabilization of cubic-structured zirconia at temperatures as low as 600-900°C, where it is otherwise unstable. IR- and LRa-observed formation of Zr2P2O7 species (cubic-structured) is suggested to act as seed species for the stabilized cubic structure of zirconia. An analogous stabilizing influence was revealed for sulfate species, however, toward cubic and/or tetragonal zirconia, and functions within the thermal stability range of the sulfate (i.e. up to 720°C).

To convert horsepower (HP) to full-load amperes (LRA), you can use the formula: LRA = (HP × 746) / (Voltage × √3) for three-phase systems, or LRA = (HP × 746) / Voltage for single-phase systems. Here, 746 is the conversion factor that represents the number of watts in one horsepower. Ensure you use the appropriate voltage based on your system to get an accurate LRA value.
A typical rule of thumb is FLA=LRA/6

Well, honey, to calculate Locked Rotor Amps (LRA) to British Thermal Units (BTU), you'll need to first convert LRA to watts by multiplying it by the voltage. Then, divide the result by 3.41 to get the BTU per hour. It's as simple as that, darling.

LRA (locked rotor amperage) is not considered. Starting current for a motor is usually in the neighbourhood of 300% of the FLA (full load amps). The FLA is taken from the motor's nameplate.

One lra (or long ton) is equivalent to approximately 1.016 metric tons. Therefore, if you're converting lra to metric tons, you would multiply the number of lra by 1.016 to get the weight in metric tons.
